I am so glad we used KDC for our dives. We did 5 two-tank dives over three days, including two night dives. The manta dives are a-maz-ing. You can't come to Kona with experiencing that magestic ballet. All dive masters were knowledgeable and provided careful, attentive guidance. The boats and service were great - even the shop girls were awesome! We saw a dozen mantas (and practically got beaten up by them!), dolpins, nudis, great variety of fish, octopi, stars, eels, etc. Woohoo! We would absolutely dive with KDC again - they're the best shop we have ever experienced. Pricing is comperable to other shops, but they charge more for gear. However, all the gear includes computers, so that was great, too.
